This paper has dealt with TiO 2/minerals compound photocatalysis material carried by natural zeolites and bentonite, and studied their degradation and discoloration characteristics to organic dyes RB under color illumination. The experiment has proved that samples not calcined have better photocatalysis capacity than those disposed at high temperature. The decoloration ratio of RB solution with TiO 2/zeolites is 100 percent and that with bentonite is 94 percent. Both XRD and TG-DTA analytical results show that anatase can be formed directly at the surface of minerals and combined solidly with the minerals, accompanied by the adjustment of mineral structures.
